Folks,
We currently have our FCP attached storage to our DS8300 running
thru SVC. No NPIV. We are trying to set up now to be Native DS8300 using
NPIV. We have a lun attached (actually 4 on on image and 1 on another )
which seem to be working but our storage admin is NOT seeing the images
actually "port log in" to the storage. In addition to that, in our
testing of lun expansion, it appears as tho when he expands the lun we
loose the partition information ( we're not sure of this one yet ).
What follows is how we were doing lun expansion and the added steps it
seems to require. We're looking for any one who's done DS8300, NPIV,
MainFrameLinux(MFL), and lun expansion.
Our past procedure to expand a lun attached via SVC running SLES9 looks
like this:
1.After the lun is expanded reboot the image.
2. Unmount the disk
3. fsck.ext3 /dev/sd?
4. fdisk /dev/sd?
p - to display the partition
d - to delete it
n - to create the new one
p - primary
1 - for part 1
take the defaults for 1st/last cyl prompts
w - write it out
5. e2fsck -f /dev/sd?
6. resize2fs /dev/sd?
7. mount /dev/sd?
This all worked as I said using SVC, DS8300, no NPIV and sles9 AND still
does as long the image is NOT rebooted...
Now when I do it with native DS8300, NPIV and SLES 10 sp2 I have
additional steps to do and I see an anomaly in that there is no
partition to print or delete when going thru the resize steps in number 4.
The additional steps are -
8. reboot the image which will not mount the resized file system due to
added /dev/sd?1 and 2 and /dev/mapper/luninfo-part1
9. We then delete the /dev/sd?1 and 2 plus a new /dev/mapper/lun info-part1
10. Remove the zfcp info
11. readd the zfcp info
12. recreate the mount point.
13. mount the file system and then all is well.
